Boom

Market position

Boom presents itself as an independent aerospace entrant reviving civil supersonic flight, citing XB-1 as the first independently developed supersonic jet and Overture as the world's fastest airliner; no third-party market share or ranking data appears in the sources beyond a 2021 TIME innovations listing and a 2021 top-50 US start-up listing referenced in its newsroom.

Boom develops both the airframe and its own engine (Symphony) rather than relying on an existing engine supplier, has flown an independently developed supersonic demonstrator, and has extended its propulsion work into a stationary natural gas turbine for AI data centers.

Technology

Overture is specified by Boom for supersonic cruise, high-altitude cruise, SAF compatibility, a stated nautical-mile range, and a passenger range, serving 600+ global routes per the company's figures (individual numeric values on the page are rendered as digit reels and are not reliably readable). Symphony is a medium-bypass turbofan purpose-built by Boom for efficient supersonic flight. XB-1 was a one-third-scale-class demonstrator that Boom says proved its approach at Mach 1. Boom also announced Boomless Cruise in February 2025 and has adapted its supersonic engine technology into Superpower, a 42 MW natural gas turbine.

Go-to-market

Direct aircraft sales and pre-order agreements with major airlines, supplier and partner agreements across aerospace (Northrop Grumman, Collins Aerospace, Safran Landing Systems, Eaton, Honeywell, Latecoere, FlightSafety International), sustainability offtake agreements (AIR COMPANY, Dimensional Energy, Climeworks), government partnerships with the US Air Force and NASA, brand partnerships (American Express, IWC Schaffhausen, Ministry of Supply), a newsroom and newsletter, and an online merchandise shop.

Commercial airlines (United Airlines, American Airlines and Japan Airlines hold Overture orders or pre-orders), premium air travelers, defense and government users engaged through prior US Air Force partnerships and a Defense Advisory Group, and operators of AI data centers requiring on-site power generation.

Geography

Headquarters and open engineering roles are in Centennial, Colorado; the Overture Superfactory is in Greensboro, North Carolina; an announced Symphony engine test site is at Colorado Air & Space Port. Overture is positioned for 600+ global routes.

History

Boom's public timeline, as reflected in its newsroom, includes a 2020 unveiling of the XB-1 demonstrator and collaborations with Rolls-Royce, Collins Aerospace and the US Air Force; a 2021 aircraft purchase agreement with United Airlines and a strategic investment from American Express Ventures; a 2022 refreshed Overture design with a Northrop Grumman alliance, an American Airlines purchase agreement, supplier agreements with Safran Landing Systems, Eaton and Collins, and the announcement of the Symphony engine; 2023 construction and milestones at the Overture Superfactory in Greensboro, North Carolina, supplier agreements with Latecoere and Honeywell, and the launch of a Defense Advisory Group; 2024 XB-1 first flight, completion of Superfactory construction, and accelerated aircraft and engine development; 2025 supersonic flight by XB-1, the Boomless Cruise announcement, a NASA imaging partnership, a Symphony engine test site at Colorado Air & Space Port, and the December Superpower turbine and funding announcement; and a February 2026 Baker Hughes generator order.
